In Switzerland September 26, 1936 vI Claims. (01. 24-207) The present invention relates to improvements in fastening devices particularly for-body gar- I ments without the use of sliders or intermediate pieces, the devices comprising a canal or channel provided on one of the parts to be coupled or fastened together and an insertable rib or beading provided on the other part.

Devices of this kind are known in which the canal, is formed by strips of fabrics sewn to the garment part. Such strips are apt to be pulled asunder by a tension acting at right angles to shaped part in order to obtain a stronger fastening. Such a reinforcement is not easily to be carried out in practice, furthermore the connection becomes very thick and bulky and can only be bent in one direction. I

In another arrangement buttons are inserted into a canal formed by strips of fabric. This arrangement has the above mentioned disadvantages as regards the strips of fabric and further the buttons tend to increase the bulkiness.

Other known devices in which the connection is obtained by means of sliders and intermediate pieces are not suitable for fastening parts of launderable clothing such as collars or cuifs to shirts as the'fastening is too cumbersome and the means are too bulky.

With the device according to the present invention the above mentioned drawbacks are overcome as the canal comprises a stiifening portion in the form of a wire insertion around which the fabric is placed. This stiffening portion effectively prevents the mating part from being pulled sideways out of the canal. The device may thus not only be used for round edged garments but also for those whichare flat when worn; it is flexible in any direction and may be fixed tothe edges of the parts to be fastened to each other without causing an essential thickening at the fastening place. Flu'ther the device may be manufactured in a simple and cheap manner and may be applied to launderable clothing as it can be washed and ironed.

By inclosingthe stiffening portion by meansof two layers of fabric cut diagonally this portion may be rendered invisible from the outside.

The wire insertion may consist of a portion of non-corrosive wire which has portions bent according to the shape of the canal and connecting parts.

Further sleeves servlngfor reinforcing may be 5 provided at the ends of the fastening. The canal may also have interruptions.

If the fastening'is used for shirt and collar connections, a covering layer may be provided on the collar to cover the connecting elements between 1c the shirt and collar.

In order to prevent the beading portion from being easily pulled out of the canal by a pull acting at right angles to the canal and to avoid the connecting means being comparatively bulky the canal consisting of the wire insertion covered by the fabric may have flattened side walls the edges of which are bent inwardly at the open slitshaped side of the canal. These edges render it difflcult for the heading tobe pulled out of the 2( canal by a pull acting at right angles to the fastening device, while the flattened .side walls permit a small thickness of the fastening device so The inner portion of the fabric covering of the canal may be sprayed with a putty that stands washing at boiling temperature and the intermediate space between the wires of the support and the outer and inner portion of the covering fabric may be filled withflakes of wool. The spraying of the inner portion of the covering fabric permits a good gliding of the beading in: the canal and the wool flakes hide the wire support from view.

Advantageou'sly the string or cord forming the core of the rib consists of braided viscose threads and is impregnated with a putty withstanding boiling and a fabric covering is glued to the string I or cord. This cord maintains its round shape during washing and ironing and when subjected to tension and compression without its flexibility being impaired. At the ends of the cord guiding pins may be provided which may be fixed to the fabric and may be provided with a guide head extending beyond the fabric. These guide pins 5 enable an easy-insertion of the beading into the canal.

In the constructional example illustrated in Figs. 1-8 I denotes a collar provided at its edge to be connected with the shirt with a rib orheading 2, which, as is shown in Fig. 3, may consist of a core 2' and of a fabric covering 2" enveloping the core. The core 2 consists preferably of tin-coated and braided copper strands and the fabric 2" is sewn to the collar l At the upper edge of the shirt 3 to which the collar is to be fastened a canal of channel 4 is formed into which the rib or heading 2 of the collar I is to be inserted in order to fasten the collar to the shirt. A covering strip or apron 5 is provided on the collar I which covers the beading 2 and the canal 4 and renders these fastening elements between collar and shirt invisible from outside.

As may be seen in Figs. 4-8 the canal 4 is provided with a stiffening insertion in the shape of a wire support 4', a sleeve 4" serving for strengthening purposes being pushed over each end portion of the wire device. A fabric 4" is placed around the supporting wire 4' and the sleeves 4", the inner portion of this fabric being sewn to the wire support 4' and the edges of this fabric projecting beyond the supporting wire and being sewn to the shirt 3. The supporting wire 4 has incomplete ring-shaped portions 4'1 adapted to the shape of the canal 4 and straight, longitudinally extending connecting portion 4': which are situated alternately on opposite sides of the canal so that the supporting wire 4 may be produced of a single piece of wire suitably bent and made of a non-corrosive material (Fig. 8).

The core 2' of the beading 2 may also be formed of a cord or string instead of a stranded copper wire, the string being impregnated by a material which is insoluble in water and is not affected by heat. so that it will always maintain its shape, that is, will not become soft nor flattened.

The string may also consist of rubber, whereby the rib is easier to be inserted into the canal and cannot be pulled sideways out of the latter. Such consists suitably of flannel.

a rubber string has the further advantage that it is not deformed by washing and ironing.

Sleeves 4" may also be provided at intermediate parts and not only at the ends of the canal.

Further instead of one layer of fabric two layers may be placed around the supporting wire of the canal, which are both out diagonally so that the wires of the supporting wire may less easily be seen through the fabric. The inner layer of fabric It is not necessary that the canal and the mating part extend over the whole length vto be connected, the canal and the mating part or both may'have interruptions or may consist of larger or smaller portions arranged at distances from each other.

The above described fastening device is also suitable for detachable connection of other parts of garments, for example for detachably fastening cuffs to shirt sleeves.

The canal illustrated in Figs. 9-*-11 is provided with a stiffening insertion in the shape of a supporting wire 6 which comprises ring-shaped portions 6' adapted to the shape of the canal and connecting parts 6" which are situated alternately at opposite edges of the canal side opening, so that the supporting wire 6 may be produced by bending of a single piece of wire. The supporting wire 6 has flattened side walls having curved edges (Fig. 10) at the open side of the canal. At each end of the canal an end sleeve 1 is provided which has the same cross-section as the support 6 and forms a continuation of the latter. The end of the support 6 is fixed to the end sleeve 1. The lower part of the end sleeve I has an offset elongation i (Fig. 12) which extends along the outside of the lower side of the supporting wire 6.

The covering 8 of fabric is placed around the supporting wire 6 and the end sleeve 1. The inner portion of the covering 8 placed in the hollow space of the canal is impregnated previous to placing the outer portion with a putty which is not affected by boiling; thereupon flakes of wool 9 are pressed into the interstices between the loops of the supporting wire 6 so that the supporting wire 6 cannot be seen from the outside after the outer portion of the covering layer has been applied. The fabric of the covering layer 8 is diagonally cut whereby the wires are less visible and a finer fabric may be used. The two outer portions of the covering fabric 8 are sewn together along a seam ID at the lower part and a straight out strip ll of fabric may be sewn in the seam for stiffening purposes. The parts of the fabric may also be glued together by an adhesive instead of being sewn together.

The core of the rib (Figs. 13 and 14) consists of a cord l2 of tightly tensioned viscose threads braided together and impregnated by means of a putty fast to boiling. Such a cord remains always round in cross-section, since washing and ironing as well as tension and compression do not affect it and its flexibility is maintained. At each end of the cord l2 a guide 'pin or tab I3 is clamped having a guide tab head l3 projecting beyond the fabric l4 placed around the cord l2 and the pin l3. The covering fabric 14 is fixed by means of an adhesive to the cord l2 and over the whole length of the latter. The guide pin i3 is provided with notched portions l3" by means of which it is held in the fabric. Around the end of the covering fabric l4 end pieces l5 are placed and fixed thereto by an adhesive whereby the guide pin I3 is prevented from "getting de- 1 tached and a stiffening of the beading is tained,

By spraying a boiling-proof putty on the inner covering fabric 8of the canal and by fixing the covering fabric H to the cord I! a diminution of the friction when the, beading is inserted into the canal is obtained and the insertion is facilitated.
